ROS2 Initialzation error about open_vins

[goldbattle]

You are correct that theses config variables should be tuned. I would first get your console logging working.
Does adding this to your node show anything?

    output='screen',
    emulate_tty=True,

The snippet didn't work well but I used the snippet from the ROS answers and it worked to get the information on the terminal.

**output='screen',
emulate_tty=True,**

I have shared the window output and also the recordings of the test.

Update Launch file

def launch_setup(context):
configs_dir=os.path.join(get_package_share_directory('ov_msckf'),'config')
available_configs = os.listdir(configs_dir)
config = LaunchConfiguration('config').perform(context)
if not config in available_configs:
return[LogInfo(msg='ERROR: unknown config: '{}' - Available configs are: {} - not starting OpenVINS'.format(config,', '.join(available_configs)))]
config_path = os.path.join(get_package_share_directory('ov_msckf'),'config',config,'estimator_config.yaml')
node1 = Node(package = 'ov_msckf',
executable = 'run_subscribe_msckf',
namespace = LaunchConfiguration('namespace'),
output={
'stdout': 'screen',
'stderr': 'screen'},
parameters =[{'verbosity': LaunchConfiguration('verbosity')},

return [node1]

Also, Can you help me with some information about the initialization process to better understand how it works and what different motion should I perform to trigger it or what params should I tune to get it triggered.
